I just noticed something, Watching ROTF earlier and I just really noticed that the transformers voices just did not seem "big" I mean when there is this 30 foot robot speaking one would think its voice would be "heavy/louder"

I was sure the voices sounded slightly different than the first movie (though Why I have not noticed before I have no clue)

So I popped in my Transformers 1 in and the voices are so much different, they have this deeper/loudness/rumble like the voices are actually coming from very large beings.

I am just curious as to what the voices are like in the 3rd one compared to the first 2. I am just a bit curious (if I base it from the TV spots I Would say closer to ROTF).

Don't get me started on the voices. Especially the fact that they went all "United Nations" and started throwing around accents from every part of the globe. As you said though, the first one had a certain tone that you'd expect of such large beings.
